Hi, with a few recent installations I get 2 buttons on the task-manager located on the same spot, instead of next to each other. When I have 2 programs open, I see one button. When I click it, the other window is in front, indicating its name in the button. When I hover my mouse over the button I see the name of the hidden window.
What could be a reason for this strange behaviour. or did I find a bug?

What you are describing sounds quite unusual. Does removing the Task Manager widget and adding it back again have any effect?

No, this does not help. I must say, and I forgot that this morning, it does not always happen. I can't put my finger on it yet when and why it starts. When I close all but one programs, and open them again it is gone and the buttons are neatly next to each other.
It is strange but I had it with different distro's (Kubuntu 11.10, Mint 12, Kubuntu12.04, Mint 13), obviously all with the KDE desktop.
Anyone an idea? Or shall I file a bug-report?

Could it be this bug? https://bugs.kde.org/show_bug.cgi?id=293687

If that's the case, here's a similar topic: viewtopic.php?f=67&t=108301&p=252354

Yes, both are the same. At the bugreport I copied my original posting from here to show there are more people who see this phenomenon.
Thanks.
